BitriseのCacheについて

最近ちゃんとテストがBitriseで走るようになった 🎉（遅い 💦） でも、各ブランチのテストのビルドに30min強かかってる 😨 一番の原因は、新しいブランチをpushした場合にはcacheが効かず 毎回Carthage bootstrapまたはpod installがBitrise上で走っていた

スクリーンショット 2019-04-25 11 36 43

もともとBitriseのstep Cache:Push と Cache:Pull というキャッシュ機能を使っていた

🎉 新しいブランチでもcacheを効かせる方法があった

ちゃんとドキュメントを読んでみた

If a build runs on a branch which doesn’t have a cache yet, 
it’ll get the cache of the main/default branch

https://devcenter.bitrise.io/caching/about-caching/

つまりBitraise/Settingsのdefault branchをmasterではなくメインの作業ブランチ（例えばdevelopとか）に設定しておけば、新しいブランチも毎回cacheが効くようになった 🎉🎉🎉

めっちゃ改善されてる 👀 ちなみにAndroidはキャッシュすると逆に遅くなるのでキャッシュ切ってたりします。 ライブラリがバイナリで配布されるからコンパイルが不要って点が違うので、CarthageのバイナリをGit管理するならキャッシュいらなくなるかもしれないですね。

ShotaKashihara commented 5 years ago

ほんと助かりました！ 感謝 @hiranodept

すべてのCarthage のライブラリ公開元がちゃんとバイナリもサポートして --no-use-binary をつけなくてもいい世界になったらいいのにな

Practice for generating accessibility identifiers

Regarding this topic https://github.com/wantedly/ios_night/issues/47#issuecomment-485722103, I've tried that. but, I have faced some problems:

So, I've solved these problems with the below code:


import UIKit

/**
 `Accessible` provides the way to find the element by a consistent name
 in UI tests.
 `generateAccessibilityIdentifiers()` creates the identifier that forms
 the combination of the class name and the property name that is styled
 like "ClassName.propertyName" and sets it to `accessibilityIdentifier`
 to each property that is UIView.
 e.g.
 - `WelcomeViewController.view`
 - `WelcomeViewController.buttonStackView`
 You can conform `Accessible` to your custom `UIViewController` or `UIView`
 and call `generateAccessibilityIdentifiers()` after all view properties
 are initalized like in the last line of `viewDidLoad()` or an initalizer.
**/

public protocol Accessible {
    func generateAccessibilityIdentifiers()
}

public extension Accessible where Self: NSObject {
    func generateAccessibilityIdentifiers() {
        #if DEBUG
            let mirror = Mirror(reflecting: self)
            generateAccessibilityIdentifiers(mirror)
        #endif
    }

    private func generateAccessibilityIdentifiers(_ mirror: Mirror) {
        // If it has no children, we treat the object as objc implementation.
        if mirror.children.isEmpty {
            generateAccessibilityIdentifiersForObjc(mirror)
        } else {
            for child in mirror.children {
                generateAccessibilityIdentifier(for: child)
            }
        }

        if let superclassMirror = mirror.superclassMirror {
            generateAccessibilityIdentifiers(superclassMirror)
        }
    }

    private func generateAccessibilityIdentifier(for child: Mirror.Child) {
        guard let view = child.value as? UIView else { return }
        guard let label = child.label else { return }

        let property = label.replacingOccurrences(of: ".storage", with: "")
        view.accessibilityIdentifier = "\(type(of: self)).\(property)"
    }

    private func generateAccessibilityIdentifiersForObjc(_ mirror: Mirror) {
        var outCount: UInt32 = 0
        guard let properties = class_copyPropertyList(mirror.subjectType as? AnyClass, &outCount) else { return }

        // swiftlint:disable:next identifier_name
        for i: UInt32 in 0 ..< outCount {
            let property = properties[Int(i)]
            let ignoreProperties = [
                "window", // Weak referenced as the property of a view controller.
                "viewIfLoaded", // `view` has been overridden by this property.
            ]
            if
                let name = property.name(),
                !ignoreProperties.contains(name),
                property.type() is UIView.Type,
                let view = value(forKey: name) as? UIView {
                view.accessibilityIdentifier = "\(type(of: self)).\(name)"
            }
        }
    }
}

private extension objc_property_t {
    func name() -> String? {
        return String(cString: property_getName(self), encoding: .utf8)
    }

    func type() -> AnyClass? {
        guard let attributes = String(cString: property_getAttributes(self)!, encoding: .utf8)
        else { return nil }
        guard let regexp = try? NSRegularExpression(pattern: "T@\"(.*)\"", options: []) else { return nil }

        guard let result = regexp.firstMatch(
            in: attributes,
            options: [],
            range: NSRange(location: 0, length: attributes.count)
        ) else { return nil }

        let range = result.range(at: 1)
        let className = attributes[range]
        return NSClassFromString(className)
    }
}
